This one sounded to me like starlings (or you might say cicadas) when they gather in clouds I started off with a length of white noise produced from importing some picture which not important I just went with any random image) and then cutting a symmetric pattern of gaps in said noise some pitch bending at the end of a lot of cleaning up the image then making sure its not too quiet overallCant seem to finish experimenting with noise generation of Adobe Audition (v3.0)
